When you're away from your favorite photo editing software, web-based Pixer.us can help you take care of some impromptu cropping and photo corrections with ease. Photo by ♡Blackangelツ.

Pixer.us fills a niche between extremely simple tools like Resizr and tools with more features than you may need like Fauxto. You can easily crop, rotate, and adjust the brightness, contrast, and saturation. There are some special effects included like the ability to color tint your photo or artificially age it, but Pixer.us really shines for its simple editing interface. Pixer.us is a free and simple tool for those times you need a quick crop and a dash of sharpening. If you have your own favorite online editing tool, sound off in the comments below.
